Product Overview NB7L14M: Clock / Data Fanout Buffer / Translator, 2.5 V / 3.3 V, 1:4 Differential, 12 Gbps, with CML Outputs and Internal Termination For complete documentation, see the data sheet Product Description The NB7L14M is a differential 1-to-4 clock/data distribution chip with internal source termination and CML output structure, optimized for low skew and minimal jitter. The device produces two identical output copies of clock or data operating up to 8 GHz or 12 Gb/s, respectively. </bR>Inputs incorporate internal 50 Ohm termination resistors and accept NECL (Negative ECL), PECL (Positive ECL), CML, LVCMOS, LVTTL, or LVDS. Differential 16mA CML (Current Mode Logic) output provides matching 50 Ohm terminations, and 400 mV output swings when externally terminated, 50 Ohm to VCC.
